This autofocus circular fisheye lens has an angle of view of 180 degrees in
all directions. It is exclusively designed for digital SLR cameras with the
APS-C size image sensor. When used in conjunction with digital SLRs with
APS-C size image sensors, it produces circular image within the frame.

The F2.8 large aperture value produces a bright image in the viewfinder and
allows photographers to take pictures in low light conditions, making it an
ideal lens for Astrophotography and Aurora photography. Due to the
quantifiable angle/area relationship it produces, this lens can be used for
scientific and arts applications such as solid angle measurements of cloud
distribution over the sky or vegetation distribution of the forest.

The minimum focusing distance of 13.5cm/5.3inch and maximum magnification
of 1:6 make it particularly useful for close-up photography. SLD(Special
Low Dispersion)glass provides effective compensation of chromatic
aberration. Sigma's Super Multi-Layer Coating minimizes flare and ghosting.
It is equipped with an inner focusing system that creates high definition
and good image quality over the whole frame. The HSM(Hyper Sonic
Motor)ensures fast and quiet autofocusing and allows full-time manual focus
override by rotation of the focus ring.
